WINDOW-SASH.

Specification of Letters Patent.

Patented Jan. 9, 1906.

Application filed March 2, 1905. Serial No. 248,010.

To LZZ whom, t may concern:

Be it known that we, I-IARRY WV. J. ED- BROOKE and FREDERICK LINDQUIST,citizens of the United States, residing at Chicago, in the county ofCook and State of Illinois, have invented certain new and useful'Improvements in Vindow-Sash, of which the followingl is aspecification.

This invention relates to improvements in means 'for el'lecting aweather-tight and locking closure between window-sash, transoms, and thelike and the frames in which they are set or hung; and the particularobj ect of such improvements is to provide a construction andarrangement which can be applied alike to either pivotally-swinging sashand sliding sash and to either metal or wood windows.

In the accompanying drawings, which form a part oi` this application,Figure 1 is a view in elevation of interlitting portions of a sash-stileand window-frame equipped with our invention in its approved form. Fig.2 is a cross-section taken tlnough a sash stile and frame and theelements which go to make up our invention. Fig. 3 is a view, partly inelevation and partly in section, of a modified form of our invention;and Fig. 4 is a detail in perspective of portions of the operativeelements of our invention.

Referring to the drawings in detail,A a a2 represent the parts of anordinary wood window-frame, to which a sash is slidably itted.

C and D represent the two parts of a divided or separable sash-stile,and it will be understood that both parts may slide t0- gether on theframe, or the part D may be pivotally swung on the part C, suchconstruction and relative arrangement being well known in the art andtherefore not shown herein. In the adjacent faces of the parts C and Dvertical grooves are cut throughout the length of said pieces, and intothese grooves are fitted metal channel-rails G G, constructed of copper,Zinc, or other suitable non-corrosive metal. These rails together form aseat, socket, or housing for a flat bar E, which m ay be oi' anysuitable metal and is thin enough to permit it to move freely betweenthe adjacent walls of the channel-rails G G. One edge of the bar E isslightly tapered, as shown in Fig. 2, thereby insuring its entrance intothe rail G on the stile part C.

As shown in Figs. 1, 2, and 4, to the bar E is riveted a strap F, theriveted end of which is slightly oilset from the main portion of thelbar. A pin K extends through the free end of the bar and projects onopposite sides thereof. This end of the bar extends through a suitableopeninfT in the rear side of a castmetal box J, which is let into thesash and is secured in place by screws which pass through the flange jof said box.

Eccentrically mounted in the box J on a pivot-pin I is a cam-lever I-I,formed with curved slots to receive the projecting ends of the pin K andwith a vertical recess h to receive the end of the bar F. It will beapparent that upon the lever being changed from a vertical to ahorizontal position, as indicated in dotted lines, the bar F will bedrawn entirely into the groove in the channel-rail G- oi the sash partD, thus releasing the part C and permitting the swinging of the part Dif it be pivotally or hingedly mounted or hung. As shown in Fig. 3,instead of forming the lever II with slots we may pivotally connect thebar F with the bar E and with the lever, in which case the stile must becut away to allow for the vertical play of the bar F. To insure theretention of the lever in its respective adjused positions, we form inits rounded edges notches h2 h2, which are engaged by the free end of aspring jg, secured to the lower part of the box J and normally pressingagainst saidlever, as clearly indicatedin Fig. 3.

In practice two levers will be used 'for operating the security-bar ineach stile where the sash is large; but for short sash one lever at ornear the center of each stile will be sul'licient for practicalpurposes. It is also our intention to use non-corrosive metal in theconstruction of the channel-bars G and the security-bar E, thus insuringthe easy movement of the latter.

Various changes may be made in the connection between the lover and thebar E and in the manner of locking the lever by spring in its adjustedpositions, all within the scope of our invention.

I'Iaving thus described our invention, what we claim as new, and desireto secure by Letters Patent, isv

1. Incombination with a frame and a sash -mounted therein, said sashhaving two-part IOO ating said bar said means comprising aneccentrically-pivoted and recessed lever connected With said bar and aspring adapted to lock said lever in its adjusted positions.

2. In combination With a frame and a sash mounted therein, said sashhaving two-part stiles as described, and the parts of the stiles havingregistering vertical grooves formed in their adjacent faces and metalchannel-hars arranged in said grooves, ametal lockingbar arranged insaid channel-bars, and means for operating said locking-bar, said meanscomprising a hollow box secured to the inner face `of the sash-stile, arecessed lever eccentrically pivoted in-said box and a strap connectingsaid lever .and said locking-bar one end of said strap fitting therecess in said lever.

3. In combination With a frame and a sash mounted therein, said sashhavin@ two-part stiles as described and the parts or. each stile como@having registering vertical grooves formed therein, channel-bars iixedin said grooves, a metal locking-bar arranged in said channelbars, andmeans for operating said lockingbar, said means comprising a box securedto the stile, a slotted recessed and notched lever eccentri callypivoted in said box, a strap connected With said locking-bar and havinga pin tting the slots in the lever, one end of said bar adapted to movein the recessed p0rtion of the lever, and a spring adapted to en-` gagethe notches in said lever and hold it in its adjusted positions.

In testimony whereof We affix our signatures in presence of twoWitnesses.
